Comprehensive review of miniDSP 2×4 HD audio processor with USB and Toslink features

Description

Design and Build Quality

The miniDSP 2×4 HD Digital Audio Signal Processor is surprisingly compact. It fits neatly into any setup without dominating your desk or entertainment center. At just 2 x 10 x 6 inches and weighing a mere 0.317 ounces, it’s lightweight yet sturdy enough to feel durable. The black metallic finish lends it a professional, understated look, blending seamlessly with other audio equipment. I’ve accidentally knocked it around a couple of times (thanks to my cat’s antics), and it has held up without a scratch. The inclusion of a remote control, power supply, and USB cable simplifies the setup process, which I appreciated—no need to scramble for additional accessories.

Performance and Audio Processing Features

What impressed me most was the 400 MHz Analog Devices SHARC processor powering this device. It handles audio processing with finesse, delivering 96 kHz internal processing for high-resolution sound. The audio clarity is nothing short of remarkable. The parametric EQ and advanced biquad programming allowed me to tweak the sound to perfection. I used the FIR and IIR filters to fine-tune my home theater setup, and the difference was immediately noticeable—crisper sound, better bass response, and smoother transitions across frequencies. The assignable FIR filter taps are a game-changer for those who are serious about room correction and crossover settings.

The 4 presets storage is a lifesaver. I set up different EQ profiles for movies, music, gaming, and casual listening. Switching between them was seamless, particularly with the remote control. Whether I was streaming audio through USB or using the Toslink digital input, the sound was consistently top-notch.

Compatibility and Versatility

One of the major upsides of this processor is its versatility. It’s compatible with analog, USB, and Toslink audio sources, making it suitable for a range of setups. I tested it with my PC, home theater system, and even my car audio setup. The USB audio streaming up to 192 kHz was particularly impressive for high-resolution files. If you’re a DIYer, speaker builder, or home theater enthusiast, this device is basically a playground for audio customization.

The wide range of processing blocks—from crossovers to delay meters—makes it ideal for those who love tinkering with audio. I played around with the delay settings to sync the audio in my surround sound setup, and the results were spot on.

Positive Features

• Compact yet powerful build, making it adaptable to various setups.
• High-resolution 96 kHz audio processing delivers exceptional clarity.
• Multiple input options (analog, USB, and Toslink) enhance versatility.
• 4 presets storage simplifies switching between customized settings.
• FIR and IIR filters elevate audio customization for advanced users.

Drawbacks to Consider

While the miniDSP 2×4 HD excels in many areas, there are a few areas of concern that stood out during my testing.

• The software interface, while functional, isn’t the most intuitive for beginners. It took me a while to understand the programming and customization options fully.
• No wireless connectivity—in an age where Bluetooth is almost a standard, this omission felt like a missed opportunity.
• The remote control feels a bit flimsy compared to the sturdy build of the processor itself.

Competing Products

When compared to other digital signal processors, this device holds its ground remarkably well. Products like the Behringer DCX2496 Ultradrive Pro offer more input/output options and wireless control but come at a higher price. On the other hand, budget options like the Dayton Audio DSP-408 lack the 96 kHz internal processing and advanced FIR filtering that the miniDSP 2×4 HD brings to the table.

What sets the miniDSP 2×4 HD apart is its compact design and versatile input options, which make it suitable for everything from home theaters to recording studios. Competitors often feel like overkill for casual users or fall short in terms of processing power.

Bang for the Buck

This device isn’t the cheapest option on the market, but it’s worth every penny for the features it offers. The price-to-quality ratio is impressive, especially with its 96 kHz processing, FIR filters, and 4 preset storage. If you’re looking for a cost-effective solution that doesn’t compromise on performance, this is a solid choice.

While it may not have all the bells and whistles of high-end competitors, the value lies in its perfect balance of functionality and affordability. For anyone who values customizable audio processing without breaking the bank, this is a no-brainer.
